Former Arizona Congresswoman Gabrielle Giffords is taking to the airwaves in hopes of persuading Congress to approve gun-control measures.

A political action committee formed by Giffords and husband Mark Kelly says it began airing a TV commercial Monday that shows images of the aftermath of four mass shootings and an on-camera appeal by Giffords for congressional action.

She's recovering from a head wound suffered in a January 2011 shooting in Tucson.
